Abstract
長い導線を持つ内視鏡鉗子や鏡視下用手術のマイクロ波照射手術器具は、マイクロ波伝送中にも発熱することが多く、冷却のための水供給装置が必要である。これにより、従来のマイクロ波等エネルギー照射手術器具は、水を通すための通路（水供給装置）が鉗子や内視鏡内に、別途、設置されていた。この水供給装置のスペースの存在により、画像ケーブルや作業用の孔径が大きく取れなかった。さらに、水供給装置の存在が、手術を困難にしていた。中心導体を中空形状にして中空管を成形し、該中空管を水の供給管等とするマイクロ波照射器具は、マイクロ波照射効率に影響を与えることなく、上記課題を解決することができることを見出して、本発明を完成した。Endoscopic forceps having a long lead wire and a microwave irradiation surgical instrument for endoscopic surgery often generate heat during microwave transmission, and a water supply device for cooling is necessary. As a result, in the conventional energy irradiation surgical instrument such as a microwave, a passage (water supply device) for allowing water to pass is separately installed in the forceps or the endoscope. Due to the space of this water supply device, the image cable and the working hole diameter could not be made large. In addition, the presence of a water supply device made surgery difficult. A microwave irradiator that forms a hollow tube with a hollow central conductor and uses the hollow tube as a water supply tube or the like can solve the above problems without affecting the microwave irradiation efficiency. The present invention has been completed by finding out what can be done.
Description
本発明は、マイクロ波照射器具、特に、医療用マイクロ波照射器具、より詳しくは、中空管を有する中心導体を有する医療用マイクロ波照射器具に関する。
なお、本出願は、参照によりここに援用されるところ、日本特許出願番号2013-235509からの優先権を請求する。The present invention relates to a microwave irradiation device, in particular, a medical microwave irradiation device, and more particularly to a medical microwave irradiation device having a central conductor having a hollow tube.
This application claims the priority from Japanese Patent Application No. 2013-235509, which is incorporated herein by reference.
マイクロ波は、消化器、肝臓、膀胱、前立腺、子宮、血管、腸管等の生体組織を低温で凝固（固定化）できることが知られている。そして、マイクロ波を用いた手術支援用の種々のデバイスが開発されている。 Microwaves are known to be able to coagulate (fix) biological tissues such as digestive organs, liver, bladder, prostate, uterus, blood vessels, and intestinal tract at low temperatures. Various devices for operation support using microwaves have been developed.
特許文献１では、「細長シャフト(１４)を含んだプローブを有するマイクロ波照射装置であって、シャフトは筒状外周壁（１８）、シャフト（１４）先端に配置された放射部（１５）、筒状外周壁（１８）の内部で放射部へ延びる伝送ライン（１７）、およびシャフト（１４）の縦方向で伝送ライン（１７）と共に延びる細長の分流部材（１９）を含んでおり、伝送ライン（１７）の側壁と分流部材（１９）の側壁は互いに接触しており、分離した２つの別々の位置にて筒状外周壁（１８）の内面に接触していることで、シャフト（１４）内に液流導路（２０、２１）のペアを提供している。使用時、冷却液は一方の導路（２０）を下降し、他方の導路（２１）を介して戻る。」を開示している。 In Patent Document 1, “a microwave irradiation apparatus having a probe including an elongated shaft (14), in which the shaft is a cylindrical outer peripheral wall (18), a radiation portion (15) disposed at the tip of the shaft (14), A transmission line (17) extending to the radiating portion inside the cylindrical outer peripheral wall (18), and an elongated diversion member (19) extending along with the transmission line (17) in the longitudinal direction of the shaft (14). The side wall of (17) and the side wall of the flow dividing member (19) are in contact with each other, and in contact with the inner surface of the cylindrical outer peripheral wall (18) at two separate positions, the shaft (14) Providing a pair of liquid flow channels (20, 21) in use, in use, the cooling liquid descends on one channel (20) and returns via the other channel (21). " Disclosure.
特許文献２では、「薬剤をマイクロ波照射部位に供給可能な中空の電極を有するマイクロ波照射装置」を開示している。 Patent Document 2 discloses “a microwave irradiation apparatus having a hollow electrode capable of supplying a drug to a microwave irradiation site”.
しかしながら、いずれの先行特許文献は、本発明の「中空管を成す中心導体を有するマイクロ波照器具並びに同軸ケーブル状の該器具、さらには、該器具が鉗子、ハサミ又はナイフの機能を有する」の開示又は示唆をしていない。 However, any prior patent document describes the present invention “a microwave illuminating instrument having a central conductor forming a hollow tube and the coaxial cable-like instrument, and further, the instrument has a function of forceps, scissors or a knife”. Is not disclosed or suggested.
現在の内視鏡手術及び直視下手術の際、超音波照射手術器具、高周波照射手術器具、マイクロ波照射手術器具により組織を凝固、止血、切断する。さらに、それらの操作と同時に生理食塩水等により該組織を洗浄、吸引することで、手術野をよく見える状態にし、該組織の器具への固着を防ぎ、さらに、マイクロ波等エネルギーの該組織への効率的な照射を実現している。
また、長い導線を持つ内視鏡鉗子や鏡視下用手術のマイクロ波照射手術器具は、マイクロ波伝送中にも発熱することが多く、冷却のための水供給装置が必要である。
これにより、従来のマイクロ波等エネルギー照射手術器具は、水を通すための通路（水供給装置）が鉗子や内視鏡内に、別途、設置されていた。この水供給装置のスペースの存在により、画像ケーブルや作業用の孔径が大きく取れなかった。さらに、水供給装置の存在が、手術を困難にしていた。In the current endoscopic surgery and direct surgery, the tissue is coagulated, hemostatic, and cut with an ultrasonic irradiation surgical instrument, a high-frequency irradiation surgical instrument, and a microwave irradiation surgical instrument. Furthermore, by washing and aspirating the tissue with physiological saline or the like simultaneously with these operations, the surgical field can be clearly seen, the tissue is prevented from sticking to the instrument, and energy such as microwaves is applied to the tissue. Efficient irradiation is realized.
Endoscopic forceps having a long lead wire and a microwave irradiation surgical instrument for endoscopic surgery often generate heat during microwave transmission, and a water supply device for cooling is necessary.
As a result, in the conventional energy irradiation surgical instrument such as a microwave, a passage (water supply device) for allowing water to pass is separately installed in the forceps or the endoscope. Due to the space of this water supply device, the image cable and the working hole diameter could not be made large. In addition, the presence of a water supply device made surgery difficult.
本発明者らは、上記課題を解決するために鋭意研究を重ねた結果、中心導体を中空形状にして中空管を成形し、該中空管を水の供給管等とするマイクロ波照射器具は、マイクロ波を表面効果で送ることができるので、マイクロ波照射効率に影響を与えることなく、上記課題を解決することができることを見出して、本発明を完成した。 As a result of intensive studies to solve the above problems, the inventors of the present invention formed a hollow tube with a hollow central conductor, and used the hollow tube as a water supply tube or the like. Found that the above problem can be solved without affecting the microwave irradiation efficiency because the microwave can be sent by the surface effect, and the present invention has been completed.

Confirmation of microwave irradiation using the microwave irradiation apparatus of the present invention was performed. Specifically, microwave irradiation was performed on the liver of a beagle dog using the microwave irradiation device 1 (medical microwave irradiation device 1) of Embodiments 1 and 2.
The confirmation result of the microwave irradiation using the microwave irradiation instrument 1 of the embodiment example 2 is shown in FIG. As is clear from FIG. 4 (a), the microwave irradiation device 1 of the embodiment example 2 was able to accurately perform microwave irradiation on the assumed affected part.
The confirmation result of the microwave irradiation using the medical microwave irradiation instrument 1 of Embodiment 1 is shown in FIG. As is clear from FIG. 4B, the medical microwave irradiation instrument 1 of the embodiment example 1 was able to accurately perform microwave irradiation on the assumed affected part.
本発明の医療用マイクロ波照射器具１は、上記の患部に正確にマイクロ波照射を行うことができる効果とは別に下記の効果を確認している。
（１）実施態様例４の医療用マイクロ波照射器具１は、ナイフで組織（患部）を切りながら、同時に、マイクロ波を該組織に照射でき、さらに、該組織の切断片を中空管５により吸引することができる。
（２）実施態様例５の医療用マイクロ波照射器具１は、鉗子で組織（患部）を切りながら（挟みながら）、同時に、マイクロ波を該組織に照射でき、さらに、該組織の切断片を中空管５により吸引することができる。
（３）医療用マイクロ波照射器具１は、長さが30cm〜300cm、外径が1mm〜30mm、内径が0.5mm〜25mmの軟性中空管構造を有すれば、内視鏡鉗子孔より挿入し、組織の止血破砕、血液等の体液を吸引、生理食塩水等の液体を撒布することが出来る。または、医療用マイクロ波照射器具１は、単独で体腔内に挿入し、組織の止血破砕、血液等の体液を吸引、生理食塩水等の液体を撒布することが出来る。
（４）中心導体２に刷毛状構造体１２（ブラシ状の突起物）を設置したマイクロ波照射部位１０により、マイクロ波は該突起物の先端から外部導体４に飛ぶことができる。これにより、該先端が直接組織（患部）に接してマイクロ波を照射することができるので、凝固、止血が容易である。さらに、刷毛状構造体１２を動かすことにより容易に組織を擦過することもできる。
（５）中空管５が吸引管８及び供給管９の機能を有するので、上記凝固、止血と同時に、凝固周辺組織の洗浄、凝固した組織、血の吸引を行うことができる。すなわち、術者は、凝固周辺組織の洗浄、吸引のための作業を大幅に省略することができ、患者にも負担を与えることがない。
（６）従来のマイクロ波照射手術器具の吸引管及び供給管の位置は、マイクロ波照射部位とは離れて位置に設置していた。すなわち、従来のマイクロ波照射手術器具を使用して組織にマイクロ波照射した場合には、吸引管の先端を該組織まで移動させて、さらに該組織の破片を吸引しなければいけなかった。しかし、本発明の医療用マイクロ波照射器具１は、マイクロ波照射部位１０の内径に吸引管８及び供給管９が存在しているので、組織にマイクロ波照射した場合には、吸引管８の先端を該組織まで移動させずに該組織の破片を容易に吸引することができるので吸引効率が高く、さらに供給管９の先端を該組織まで移動させずに該組織の洗浄を行うことができるので洗浄効率も高い。
（７）従来のマイクロ波照射手術器具の吸引管及び供給管の位置は、マイクロ波照射部位とは別途に設置していた。すなわち、従来のマイクロ波照射手術器具を使用して組織にマイクロ波照射する場合には、吸引管の先端及び供給管の先端の存在が術者の視野を狭めていた。しかし、本発明の医療用マイクロ波照射装置１は、マイクロ波照射部位１０の内径に吸引管８、供給管９が存在しているので、術者の視野を狭めることはない。
すなわち、本発明の医療用マイクロ波照射装置１は、従来のマイクロ波照手術器具と比較して、極小化に成功し、加えて、組織の凝固、止血、洗浄、吸引が容易に行うことができ、さらに、それらの操作を短時間かつ効率的に行うことができる。The medical microwave irradiation instrument 1 of the present invention has confirmed the following effects in addition to the effect of accurately performing microwave irradiation on the affected area.
(1) The medical microwave irradiation device 1 of the embodiment example 4 can simultaneously irradiate the tissue with a microwave while cutting the tissue (affected part) with a knife. Can be aspirated.
(2) The medical microwave irradiation instrument 1 according to Embodiment 5 can simultaneously irradiate the tissue with microwaves while cutting (squeezing) the tissue (affected part) with forceps, and further, cutting a piece of the tissue. Suction can be performed by the hollow tube 5.
(3) If the medical microwave irradiation device 1 has a flexible hollow tube structure with a length of 30 cm to 300 cm, an outer diameter of 1 mm to 30 mm, and an inner diameter of 0.5 mm to 25 mm, it is inserted from the endoscope forceps hole. Then, hemostasis of tissues, body fluids such as blood can be sucked, and liquids such as physiological saline can be distributed. Alternatively, the medical microwave irradiation instrument 1 can be inserted into a body cavity alone, hemostatically crushing tissue, sucking body fluids such as blood, and distributing liquids such as physiological saline.
(4) By the microwave irradiation part 10 in which the brush-like structure 12 (brush-like protrusion) is installed on the center conductor 2, the microwave can fly from the tip of the protrusion to the external conductor 4. Thereby, since the tip can be directly in contact with the tissue (affected part) and irradiated with microwaves, coagulation and hemostasis are easy. Further, the tissue can be easily scraped by moving the brush-like structure 12.
(5) Since the hollow tube 5 has the functions of the suction tube 8 and the supply tube 9, simultaneously with the coagulation and hemostasis, the tissue around the coagulation can be washed, the coagulated tissue and blood can be sucked. That is, the operator can largely omit the work for cleaning and aspiration of the tissue around the coagulation, and does not give a burden to the patient.
(6) The positions of the suction tube and the supply tube of the conventional microwave irradiation surgical instrument are set apart from the microwave irradiation site. That is, when a tissue is irradiated with microwaves using a conventional microwave irradiation surgical instrument, the tip of the suction tube must be moved to the tissue, and further, the tissue fragments must be sucked. However, in the medical microwave irradiation instrument 1 of the present invention, since the suction tube 8 and the supply tube 9 exist on the inner diameter of the microwave irradiation site 10, when the tissue is irradiated with microwaves, the suction tube 8 Since the tissue debris can be easily sucked without moving the tip to the tissue, the suction efficiency is high, and the tissue can be washed without moving the tip of the supply tube 9 to the tissue. So cleaning efficiency is high.
(7) The positions of the suction tube and the supply tube of the conventional microwave irradiation surgical instrument are set separately from the microwave irradiation site. That is, when the tissue is irradiated with microwaves using a conventional microwave irradiation surgical instrument, the presence of the tip of the suction tube and the tip of the supply tube narrows the visual field of the operator. However, in the medical microwave irradiation apparatus 1 of the present invention, the suction tube 8 and the supply tube 9 are present on the inner diameter of the microwave irradiation site 10, so that the operator's visual field is not narrowed.
That is, the medical microwave irradiation apparatus 1 of the present invention succeeds in minimization as compared with the conventional microwave surgical instrument, and in addition, the coagulation, hemostasis, washing, and suction of the tissue can be easily performed. Furthermore, these operations can be performed efficiently in a short time.
